Maximum gain that can be applied by the AVC in expander
mode.
0x0 = 0dB gain
0x1 = 6dB of gain
0x2 = 12dB of gain

0x0 = 0mS LBI
0x1 = 25mS LBI
0x2 = 50mS LBI
0x3 = 100mS LBI

Enable Hard Limiter Mode
0x0 = Hard limit disabled. AVC Compressor/Expander is
enabled.
0x1 = Hard limit enabled. The signal is limited to the
programmed threshold. (Signal saturates at the threshold)
Reserved
Enable/disable AVC
0x0 = Disable
0x1 = Enable

Threshold is programmable. Use the following formula to
calculate hex value:
Hex Value = ((10^(THRESHOLD_dB/20))*0.636)*2^15
Threshold can be set in the range of 0dB to -96 dB
Example Values:
0x1473 = Set Threshold to -12dB
0x0A40 = Set Threshold to -18dB
